# 8sh A/B (DESIGN.md §18 follow-on): does the explicit bridge_circulation
# repair mutation (qi6 mechanism (a)) actually clear 'level N not connected'
# fails that the graded comparator-key signal (mechanism (b)/(c)) measured
# negative on? Same qpk protocol as qi6: equal-budget ON vs OFF, both arms
# finished with the standard finish-time --collapse (94g) so the comparison
# is apples-to-apples on the final collapsed score.
#
# Authoritative metrics: total fail count and 'not connected' fail count, read
# from the .fails file homemaker-fitness writes (evolve.py itself only prints
# n_fails, not the fail list). Each run appends one TSV row so partial results
# survive an interrupt.
#
# Usage: experiments/run_8sh_ab.sh
